Abstract

Cholesteric laminate material has at least one 3-dimensionally crosslinked, oriented cholesteric layer (I) showing a homogeneous interference line pattern over the entire thickness. Independent claims are also included for the following: (a) cholesteric pigment comprising layer(s) (I) with an average particle size of 5-50 mu m and thickness of 0.2-5 mu m; (b) compositions containing the pigment(s); (c) polarizers, comprising the laminate and optionally a substrate foil; (d) broad band polarizers comprising laminates with a total thickness of about 2-50 mu m (without substrate film) and 3-20 cholesteric layers with attuned reflection maxima; and (e) the production of the laminate with layer(s) (I).
